Adaptations in growth factor requirements for lactic acid bacteria.
Adaptive processes in bacteria, whereby growth of organisms in deficient or drug-enriched media can be initiated through the production of new or latent enzyme systems, have been widely described. Reviews on this subject by Karstrom (1938), Dubos (1940), and Monod (1947) have provided examples of adaptation in bacterial carbohydrases and proteases, in enzymes of fermentation and glycolysis, and...
متن کاملLactic acid bacteria as probiotics.
A number of Lactobacillus species, Bifidobacterium sp, Saccharomyces boulardii, and some other microbes have been proposed as and are used as probiotic strains, i.e. live microorganisms as food supplement in order to benefit health. The health claims range from rather vague as regulation of bowel activity and increasing of well-being to more specific, such as exerting antagonistic effect on the...
متن کاملLactic acid bacteria as probiotics*
Lactic acid bacteria (LAB) are commonly found on human and animal mucous membranes in dairy products and naturally on some plant surfaces. They are normal residents of the gastrointestinal tract of human beings. Several species are commercially used in production of fermented milks, yoghurt, other dairy and meat products, as well as other foods. The antimicrobial activities of LAB have been kno...
متن کاملAntimicrobial Effect of Lactic Acid Bacteria against Common Pathogenic Bacteria
Abstract Background and Objective: Probiotics are living microorganisms that have beneficial effects on the health of digestive system. The aim of this study was to evaluate the antimicrobial ability of acidic and neutral supernatants (culture supernatant) of lactic acid bacteria against common bacterial pathogens. Meth...
متن کاملLactic acid bacteria as a cell factory for riboflavin production
Consumers are increasingly becoming aware of their health and nutritional requirements, and in this context, vitamins produced in situ by microbes may suit their needs and expectations. B groups vitamins are essential components of cellular metabolism and among them riboflavin is one of the vital vitamins required by bacteria, plants, animals and humans. Here, we focus on the importance of micr...
